We just moved into our 8 yr old home two months ago. We discovered after purchase that our attic in the garage was not insulated and have arranged to have R-30 insulation blown in. I want to place a few pieces of 3/4" plywood trimmed to fit through access. My concern is the existing electrical lines which have been run over the 2'x10' rasters. I was considering notching the rater to recess the electrical. Is this advisable or should I place wood tabs on each side of cable that crosses the raster?
